Effect of shear stress field on the sizes of macromolecules in polymer solutions and blends

Equations describing relationship between the binodal and liquidus curve sh ifts, induced by a shear stress field, and the macromolecular stretching co efficient are proposed for the polymer-polymer and polymer-solvent systems. The concentration dependences of the shear flow-induced variation of the m acromolecular dimensions are calculated for the systems with crystalline an d amorphous phase separation.
